The currencies under the Payments tab on the Settings page are a list of all currencies available for your installed payment gateways. Installing payment gateways that support other currencies should add more options to the list. However, you might want to use a currency not supported by any payment gateways. This would be a common scenario for a Bank Transfer-style gateway. In this case, it would be helpful to add a custom currency to your theme.

Adding a currency is easy. Currencies can be added in either a plugin or a child theme. You’ll want to first follow our guide on how to create a child theme, or look at WordPress’s guide to writing plugins.

Payments has a single class that deals with currencies. It is called APP_Currencies. This class allows you to register new currencies, get information about installed currencies, or format prices using the currency’s symbol.

To add a currency, you’ll want to use APP_Currencies::register_currency() on the init hook.

add_action( 'init', 'myplugin_add_currency' );
function myplugin_add_currency(){
 
    // Give your currency a name and symbol
    $args = array(
       'name' => 'My Currency',
       'symbol' => 'M'
    );
    // The first argument is the currency code. Usually a 3 letter code. ( United States Dollars  = USD )
    APP_Currencies::add_currency( 'APP', $args );
 
}

note:Please change the

>

to this character >

Adding this function will add ‘My Currency’ to the list of available currencies on the list. Selecting it will cause prices to be rendered as ‘M10’.
